The Capture Of A Stronghold
While Bruce had by his energy and courage been wresting Scotland, step by step, from the English, no serious effort had been made by the latter to check his progress. Small bodies of troops had from time to time been sent from the north; but the king had made no great efforts, like those of his father, to reduce the country to obedience by the exercise of the whole strength of England. Edward II differed widely from his father in disposition. At times he was roused to fits of spasmodic energy, but for the most part he was sunk in sloth and supineness. He angered and irritated his barons by his fondness for unworthy favourites, and was engaged in constant broils with them.

So called governors of Scotland were frequently appointed and as often superseded, but no effectual aid was given them to enable them to check the ever spreading insurrection. But Perth was now threatened by Bruce; and the danger of this, the strongest and most important northern fortress, roused Edward from his lethargy. A fleet was fitted out for the Tay. Troops, under the Earl of Ulster, were engaged to be transported by an English fleet of forty ships, supplied by the seaports, and intended to cooperate with John of Lorne in the west. Edward himself, with a powerful army, accompanied by the Lords Gloucester, Warrenne, Percy, Clifford, and others, advanced into Scotland as far as Renfrew. Bruce could oppose no effectual resistance in the field to so large a force, but he used the tactics which Wallace had adopted with such success. The country through which the English were advancing was wasted. Flocks and herds were driven off, and all stores of grain burned and destroyed. His adherents, each with their own retainers, hung upon the skirts of the English army, cutting off small parties, driving back bodies going out in search of provisions or forage, making sudden night attacks, and keeping the English in a state of constant watchfulness and alarm, but always retiring on the approach of any strong force, and avoiding every effort of the English to bring on an engagement.
